agent-config-setup

agent-config-setup is a skill for Claude Code, Codex from ofershap/create-agent-config. It costs 43 tokens per session (356 once invoked), scanned A, original, MIT.

A setup tool that creates instruction files for several coding-agent tools by examining a project's files. It can create formats such as CLAUDE.md, AGENTS.md, Cursor rules, and Copilot instructions.

In plain words
What is it for?
Use it when starting or documenting a project for AI agents, including TypeScript, React, Next.js, Python, Go, Docker, and monorepos, or when generating files in automated scripts.
Why use it?
It avoids writing the same project guidance separately for each coding assistant. It detects the project's languages, frameworks, tests, and other tools so the files reflect the project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agent-config-setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Agent Config Setup

Use this skill to generate AI agent configuration files for a project. One command detects the stack and writes config for every major AI coding tool.

Usage

npm create agent-config

Or with npx:

npx create-agent-config [directory]

Supported Formats

Format Agent
.cursor/rules/*.mdc Cursor
CLAUDE.md Claude Code
AGENTS.md Universal standard
.github/copilot-instructions.md GitHub Copilot
.windsurfrules Windsurf
.clinerules Cline

What It Does

  1. Scans your project for stack signals (package.json, tsconfig, Dockerfile, etc.)
  2. Detects frameworks, languages, test tools, CI setup
  3. Asks which config formats you want
  4. Writes tailored config files with project-specific conventions

Key Patterns

  • Auto-detects: TypeScript, React, Next.js, Python, Go, Docker, Monorepos, and 20+ more
  • Each format gets the same project knowledge, adapted to the tool's config syntax
  • Safe to run on existing projects — won't overwrite files without confirmation
  • Non-interactive mode: npx create-agent-config --yes for CI/scripting
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
